A. File level encryption with alphanumeric passwords
B. Biometric authentication and cloud storage
C. Whole disk encryption with two-factor authentication
D. BIOS passwords and two-factor authentication

Answer: C

Explanation:

Combining whole-disk encryption with two factor authentication would further increase protection.
